SANTO DOMINGO, Dominican Republic (AP) - Former major league pitcher Pascual Perez, who had a troubled 11-season career that included two suspensions for drug use, was killed at his home in the Dominican Republic in an apparent robbery, police said Thursday.

Perez, who last played for the New York Yankees in 1991, was found with a severe head wound in a town west of the capital, Santo Domingo, and there was evidence at the scene to suggest that whoever killed him had been searching for money, said Joel Valdemiro, a prosecutor who is involved in the investigation.

No one was in custody and authorities did not reveal whether they had any suspects. Police said there were several assailants and that the house in the town of Don Gregorio appeared to have been ransacked.

"It's an act of criminality, unfortunately," Valdemiro said.

Perez's brother Carlos, a former pitcher for the Dodgers, confirmed his death.

Perez's ex-wife Maritza Montero found his body about 8:30 a.m. Thursday and investigators said he appeared to have been slain about eight hours earlier.

The precise cause of death has not been determined but officials said Perez, who had suffered severe kidney problems in recent years, had a fractured skull from a blow to the head.
